I have been having issues with external devices being mounted on my MacBook Pro that includes
External Drives
USB Pens
If they are connected when machine is first switched on they are fine and I can unmount and remount them, but if they are not connected on start up, I can still mount them if, and only if it is within 6 to 10 minutes after that I have to do a restart.
This includes powered drives and non powered drives.
If I turn SIP off then all works perfectly, I know it is not recommended but it is a magic button for me.
I have tried SMC Reset, and PRAM Reset and nothing will cure it.
